Save messages

Hi Gabriele,

The messages are not saved by default. You can change that behavior by injecting your own server-side logic. It can be done in a "beforePublish" event handler. For example, the following event handler would save every single published message in the "Messages" table:

1. /* global Backendless */
2. /**
3. * @param {Object} req The request object contains information about the request
4. * @param {Object} req.context The execution context contains an information about application, current user and event
5. * @param {Object} req.message
6. * @param {Object} req.publishOptions
7. * @param {Object} req.deliveryOptions
8. *
9. * @returns {Object|Promise.<Object>|void} By returning a value you can stop further event propagation and return
10. * a specific result to the caller
11. */
12. Backendless.ServerCode.Messaging.beforePublish('*', function(req) {
13. Backendless.Data.of( "Messages" ).save( req.message );
14. });

Perfect, done! Thank you very much!
